The exact percentage (concentration) of composition is not shown due to component range variations, withheld or trade secret ingredients. Skin Contact Wash off immediately with plenty of water. Eye Contact _Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. If symptoms persist, call a physician. Inhalation Remove to fresh air. If symptoms persist, call a physician. Ingestion Not a normal route of exposure. Induce vomiting, but only if victim is fully conscious. Consult a physician if necessary. Notes to Physician Treat symptomatically. Flammable properties Not flammable. Suitable Extinguishing Media Use extinguishing measures that are appropriate to local circumstances and the surrounding fire. Unsuitable Extinguishing Media Water. Specific hazards arising from the chemical Molten flux 1100°C in contact with water may explode.
